v STILL.

Application filed June 20, 1922. Serial No. 569,614.

To all whom it 'lna-g concern:

lie it known that i, Max F. DE Bama- GETIIY, citizen of the United States, residing at .llouston, in the county of Harris and State of Texas, have invented certain new and useiul lmlirovement in a Still, of which the following is a specification.

This invention relates to new and useful iuig-n'ovements in a still.

One object ot the invention is to provide a still specially designed for use in the distillation of hydrocarbon, and whereby the elements of high gravity may be separated 'lroi'u the heavier elements.

Another object ot the invention is to provide a still of the character described having a drum located within the boiler and through which the petroleum or other hydrocarbon to be distilled passes before it enters the boiler, said drum being provided for the purpose of collecting sediments and other heavy elements to prevent their being deposited in the bottom of the boiler. lVithout this drum the heavy elements and solid matter in the fluid would settle on the bottom of the boiler forming a thick heat retaining coat which would soon cause the bottom of the boiler to be burned out, with the result that the contents of the boiler would he suddenly discharged into the turnace causing an explosion. To prevent this the drum has been provided.

Another object of the invention is to pro vide a still of the character described provided with a drum within the boiler through which the hydrocarbon passes before being discharged directly into the boiler, said drum being provided for the further purpose ot' relieving the boiler of an excessive amount of pressure.

A still further feature of the invention resides in the provision of a still so constructed that the petroleum or other hydrocarbon to be distilled is discharged into the bottom of the boiler through a nozzle so located that there will be a constant current or wave of fluid passing along the bottom of the boiler and keeping said bottom cleansed of settlings or sediment which would otherwise tend to collect on and adhere to the bottom.

i l ith the above and other objects in view the invention has particular relation to certain novel features of construction, operation and arrangement of parts, an example of which is given in this specification and illustrated in the accon'ipanying drawings, wherein Figure 1 shows a vertical sectional view of the still.

Figure 2 shows a transverse sectional view taken on the line 22 of Figure 1.

Figure 3 is an end view of the boiler and,

Figure l is a transverse sectional view of one of the domes employed taken on the line +lt of Figure 2.

In the drawings, the numeral 1 designates the boiler, under which there is a furnace 2. The boiler is filled with hydrocarbon through an inlet line 3. This line is formed into a coil 1 within the furnace and is controlled by a back pressure Valve 5. It enters the end of the boiler near the top and within said boiler branches and enters the drums G, 6, one end of each of which projec'ts out through the opposite end of the boiler and are securely anchored to said end. Leading from the last mentioned ends of the drums there is an outlet pipe 8 which turns downwardly and inwardly forming a nozzle 9, which enters the adjacent end of the boiler near the bottom thereof and which is controlled by a gate valve 10.

The boiler 1, at each end is formed with vertical cylindrical domes, 11, 11. domes have the central fines 12, 12 which are "fastened at their upper ends to the top of the domes, and have inlet openings 13, 13. The lines 12 are controlled by a suitable gate valve as 14. located near their upper ends. The lines depend into the boiler, and their lower ends are connected by a connecting pipe 15, leading from which to the central dome 16 of the boiler there is a pipe 17 A line 18 leading from the dome 16 enters a suitable condenser (not shown).

lVithin the domes 11 there are the disclike inverted conical shaped battles 19 spaced apart. These battles are anchored at their outer edges to the domes 11 and at their inner edges to the lines 12 and opposite each battle there is secured around each dome the annular plates 20. These plates radiate the heat and keep the battles 19 comparatively cool. The fluid in the boiler is kept at a high degree of ten'iperature and the lighter elements are constantly being given off and passed up through the baffles 19, which are perforated, and enter the upper ends of the fines 12 and then pass downwardly through said fines, and through the pipes 15 and 17 into the dome l6 and thence out through the These 8 Ill) line 18 into the condenser. The heavier particles are arrested by the baflles 19 and drop back into the boiler to be again broken up by the heat therein, the lighter elements constantly passing up through the domes 11 and the heavier elements being arrested and dropping back into the boiler. A very high percentage of the hydrocarbon in the boiler is thus distilled and the lighter elements are extracted therefrom.

As hereinbefore indicated the fluid, before entering the boiler proper, passes through the drums 6. These drums are of considerable capacity and the fluid contained therein is given an opportunity to settle, the solid particles and refuse settling to the bottom of the drums. The exposed end of each drum has a removable head 21 permitting the cleansing of the drums at proper times. A high percentage of this solid matter is thus collected from the fluid before it enters the boiler so that there will be only a small amount of sediment retained in the fluid entering the boiler proper, and the discharge of the fluid through the nozzle 9 along the bottom of the boiler will prevent this from settling and adhering to the bottom of the boiler, thus protecting said bottom from the liability of burning out.

WVhat I claim is 1. The combination with a still including a boiler, of a plurality of reacting drums mounted therein, and one end of Which projects outside of the boiler, a detachable hcad carried by the outer ends of said drums, an inlet pipe formed ith heating coils entering one end of the drum and a discharge nozzle leading from the outer end of the drum and entering the boiler.

2. In combination still including a boilor, a reacting drum anchored therein, one end of which projects out of said boiler, a detachable head carried by said end, a heating coil, an inlet line leading from said COll and entering said drum, a backpressure valve controlling said line, a dischargeline leading from the drum and terminating in a nozzle within the boiler, through which the contents of the drum may be discharged into the boiler, and a ralye for regulating the flow or fluid through the discharge line.

3. In combination a still including a boiler, a reacting drum within said boiler, one end of Which projects out beyond the boiler end, and is provided with a detachable head and is anchored to said end, a. heater coil, an inlet line leading from said coil d entering said drum, a discharge nozzle leading from the projecting end of said drum, and terminating in a nozzle which enters the boiler through which the contents of the drum may be discharged into the bottom of the boiler and valves controlling said lines.

In testimony whereof I have signed my name to this specification.
